A copper based HSF from a Coolermaster EP5-6H11

The system I used :

Mainboard : ABIT BX133 RAID

Processor : Celeron 1.0A (Tualatin 256Kb L2 cache)

Cooler : copper based EP5-6H11 8x8 SUNON PTB1 fan

RAM : 256mb SDRAM Corsair PC150 2-2-2

VGA : ASUS V7100 PRO OC @280/280mhz

The story :

I wanted to put a big copper HSF on my Tualatin CPU, but they are always expensive and/or I can't use them

(Alpha PAL 8045 for instance isn't for socket 370 CPU)

So I decided to built one using some stuff i had yet

I had a good old COOLERMASTER EP5-6H11HSF and a very good SUNON 8X8 ball bearing fan

I only bought a 80X60X5mm copper plate to do the base of my HI-TECH HSF!

 Some Pictures :

First i took my EP5-6H11 HSF and I get rid of its little and noisy fan,then I lapped the base till removing the base step

After that I cut it in two halves and made the surfaces rough to improve air thermal exchange :

I set the base to obtain a final 8X8 heatsink with a good copper base:

Then I assembled the parts  (using steel screws and thermal compound between the lapped surfaces ) : 

That's all, I finally got my home made copper HSF !

Here you are some shoots of my system parameters :

This is a screen with the old good ADDA HSF with the SUNON FAN (note SETI running underground) :

And this is the results with the new copper-based EP5 and the same SUNON FAN (under SETI) :

 What could I say? I'M VERY SATISFYED ! My Self-made Copper-based HSF works very good!

And it is silent thanks to the SUNON  FAN !

Disclaimer :

These results where reached on my system, and I can't guarantee this kind of HSF works as good on a AMD or other HOT CPU.....

Anyway it would be an interesting bet running a K7 or Duron with a self-made copper-based HSF ,and comparing the T °C

with a Alpha PAL8045 HSF!

have fun!
